TOY TYPE-WRITER.

Specification of Letters Patent.

Patented Dec. 1, 1914.

Application filed January 28, 1914. Serial No. 814,868.

To all whom it. may concern:

Be it known that I, ARTHUR B. CARROLL, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Toy Type-Writers, of which the following is a specification.

This invention relates to a toy type-writer machine.

The object of the invention is to provide a type-writer machine constructed of few parts and that can be manufactured at little cost to serve the purposes of children for amusement.

The invention is illustrated in the accompanying drawing in which,

Figure 1 is a top plan view. Fig. 2 1s a front elevation. Fig. 3 is an end view. Fig. 4 is a vertical cross-section. Fig. 5 is a vertical section showing the rubber rollers, and Fig. 6 is a view of the guard fingers.

Referring to the drawing the base-plate, 1, is flat and has a down-turned flange, 2, that will sit on any table. A sheet-metal back-plate comprises a vertical part, 3, the bottom of which is bent laterally at a rightangle and has a horizontal position as at 4, and forms a foot that rests upon the said base-plate. The u per part of the vertical back is also bent orward at a right-angle and forms a horizontal part, 5, and then is bent upward to a vertical position and forms a face plate, 6. Two bolts, 7, are employed :to' act as stays or braces to give stiffness to the back plate; the lower ends of these two 'bolts pass through the foot, 4," and also through the base-plate, 1, and the ends are suitably fastened. The lower ends of the two bolts, 7, are farther fromthe vertical part, 3, of the back plate than the upper eiids, and the latter are secured to the hori- 2o'ntal part, 5, close to said vertical part; this gives an inclined osition to the said Ibolts, 7 and thereby t ey serve better as braces for the vertical part, 3.

The face plate, 6, at its front has a plural number of guidebooks, 8, formed by punching one end outward, said hooks to form a slideway for thesvertical fiat platen, 9, of the paper-carriage, two or three of the said guide-hooks, 8, point downwardly, and two or three others point upwardly, and the horizontally-moving platen, 9, base straight ,upper flange, 10, along its entire length and a similar lower flange, 11. The up er flan e, 10, engages those guide-hooks t at point down, and the lower flange engages those hooks, 8, that point up, and thereby the said platen, 9, is free to slide horizontally through the guide-hooks.

Attached to the platen, 9, is a tube, 12, which hangs below the carriage; this tube has at its top a longitudinal slot, 13, extending the entire length, the tube serves to hold the paper on which the type impressions are to be made. The paper is placed in the tube by entering one end of a sheet downwardly through said slot, and the sheet will coil within the tube leaving the last end of the paper projecting upward across the platen, 9, of the carriage, and the ty e impressions are made on this last part of t e paper.

A horizontal bar, 14, has its ends attached to the platen said ends being bent rightangled, and the bar itself stands off a little in front of the platen, leaving a space between; and the paper that projects upward passes through this space, so that in the op- The apenad'uster is mounted on thecarriage and comprises two parallel metal rods, 15, 16, one being mounted in end bearings, 17, and extending across the front surface of the platen, 9, and the other rod in suitable bearin s and extending across the rear surface of the platen; theplaten, 9, separates the two rods. Each of the rods, 15, 16, has two rubber sleeves, 18, and the platen has two slots, 19, that open entirely through from the front to the rear; the slots are a little longer than the rubber sleeves, and thus two sleeves--one on each of the two rods, may be close together, a sleeve on the rear rod contacts with a sleeve on the front rod, and that part of the sheet of pa per that projects upward from the tube, 12, is gripped between the said contacting rubber sleeves. At each end the front rod, 15, is provided with a knob, 20, which may be grasped by the hand to facilitate its turnmg, and thereby the paper may be raised the proper distance for the next lower line of type-writing.

'The feed-device to move --forward the pa-iper-carriage. the proper distance for the width of one type, synchronically with respect to making the impression of a type consists of ratchet-teeth, 21, formed on the straight edge of the upper flange, 10, of the platen, 9; each ratchet tooth represents the width of one type. A feed-pawl, 22, has a point-end, 23, see Fig. 2, that engages with the ratchet-teeth, 21, and said pawl is jointed by a pivot-pin, 24, to the downward end of a spacer-le\er, 25, that is secured by a pivot, 26, to the said vertical face-plate, (5. The spacer-lever has an angle-bend of nearly right-angle form and the pivot, 26, on which this lever turns is at the anglebend and the long arm of the lever extends approximately horizontal, while the short arm extends downward and at its end has the said pivot-pin 24. Thus the feed-pawl, 22, hangs suspended from the right-angled spacer-lever, it will be understood that the lower end of the short arm of the spacerlever in moving on its pivot, 26, describes an arc of a circle, and the length of this are defines the extent of throw made by the feed-pawl, 22, when acting on the ratchetteeth, 21, and this throw is the width of one type. A suitable. wire spring, 27, acts on the under side of the feed-pawl, 22, and by pressing one end" thereof upwardly causes the point, 23, at the opposite end to keep in engagement with the teeth, 21. The said point-end, 23, of the pawl has up-anddown movement on its pivot, 2a; the point end is kept in proper position by a rigid horizontally-bent guide-finger, 28.

The spacer-lever, 25, may be depressed manually at the end of each word, to cause a space to be left on the sheet of paper but to move the paper-carriage to suit the successive impressions of the several types reguired to spell a word, said spacer-lever is epressed by connecting mechanism that operates at the same time the type-wheel, 29, is tilted toward the-platen to make a type impression.

The type characters, 30, that imprint are fixed on the circumference or rim of the wheel, 29, in the same relative position on the type-wheel that a tire has on a wagon wheel. This type-wheel turns in a plane that is approximately horizontal, and has a knob, 31, by which it is turned on an upright spindle, 32, fixed at the top of a movable standard 33. I

The type-wheel has on its top face typecharacters arranged in a circle, and an index prong, 50, has a shank, 51, extending entirely across and fixed on top of the standard, 33, and below the wheel, 29; this shank extends in a radial direction relative to the wheel and has a U-shaped curve, 52, at the rim-edge of the wheel that doubles back over the said rim-edge, and the index prong.50, is, thereby held stationary above the top face of the wheel. Each type character of the set on top of the wheel, is individually so disposed relative to the corresponding character of the set on the rim of the wheel, that when the letter, A, for instance, on top shows directly in position coincident with the index prong, 50, the letter, A, on the rim will be in position to make an impression on the paper. A guard consists of a fiat shank, 53, having two hook-shaped parallel edges, and at one end provided with two upturned guard-fingers, 54, separated from each other by an open space the width of the widest type character. The two hook-shaped parallel edges have a friction grip on the shank-bar, 51, that extends entirely across the top of the standard, 33; the friction grip is sufficient to keep the guard from sliding accidentally, but it may be moved by applying a little force; the fingers project at the wheel-rim diametrically opposite the index prong, see

Figs. 1 and'3. The type guard does not' revolve 'witlr'the wheel, but remains stationary like the index prong. When the type-wheel is tilted to make an impression, the particular type to be imprinted has position at the open space between the two guard fingers, 54:, where it may contact with the paper, and the two guard fingers, 5 1, cover the two type characters at either side and prevent them from contacting with the paper.

The revoluble type-wheel, 29, is carried on a suitable standard, 33, which in the present instance, comprises two parallel upright sheet-metal bars, connected by bolts,

31. The two upright bars, 33, have their lower ends firmly secured to a foot bar, 35, mounted on a pivot pin, 36, supported on a bearing, 37; the standard, 33, and the footbar, 35, are at a right angle with respect to each other.

The type-wheel is tilted in one direction, that is away from the platen, 9, by a spiral spring, 38, and in the opposite direction,

that is, toward the platen, by a hand-lever,

39, that engages said foot-bar; this handlever has its pivot, 40, on a bearing attached to the base-plate. It will be seen when the hand-lever, 39, is depressed by the operator, the type-wheel will be tilted toward the platen, 9, and one of the type characters on the rim of the type-wheel will then contact with the paper that is in front of said platen, and the said character will make an ink-impression on the paper.

'lne means that connects from the spacerlever, 25, to the foot bar, 35, is an upright rod, 41. The upper extremity of thls rod has a right angles prong, 42, that projects,

lateral prong, 44, that enga the end of the foot-bar, 35, see Fig. 4. he lower part of the rod, 41, passes freely through a hole, 45, in the horizontal part, 5, of the backplate, and above said horizontal part, 5, the rod itself is bent to form a horizontal ortion, -16. The highest part of the face p ate, 6, has a short arm, 47, extending backward, and the said spiral spring, 38, in a state of distention has-its upper end connected with the short arm, 47, and the lower end of the spring is connected with thesaid horizontal portion, 46, of the rod, thus the sprin con stantly exerts an up-pull on the sai rod; the spring therefore serves to tilt the typewheel away from the platen. hen the hand-lever, 39, is depressed by the operator to cause an ink impression of type to be made on the paper, said hand-lever must overcome the up pull tension of the spring, 38.

A device to apply ink to the t pe characters, 30, on the rim of the whee consists of two rollers, 48, which are placed one diametrically opposite the other, so as to lightly touch or bear on the type characters; each roller, 48, is supported by an inclined arm, 49, and the said two arms are fixed to the standard, 33, see Fig. 2.

To operate the machine, turn the typewheel until the type-character that is wanted coincides with the index rong, 50; then depress the hand-lever, 39; if this happens to be the last letter in, the word, then depress the spacer-lever, 25, to make a space.

When a line has been completed depress the feed-pawl, 22, and draw the carriagetoward the right hand, and then grasp one of the knobs, 20, and turn it in order to raise the sheet of paper to the proper distance to commence another line.

From the foregoing description the operation of the ty ewriter will be understood. Having thus escribed my invention what I claim and desire to secure by Letters Patent is 1. In'a type-writer machine, the combination of a vertical plate, 6, provided with guide hooks, 8, one end of each hook being attached to the plate and the other end free; a carria e having a vertical flat platen provided with two horizontal edges-one above and one below, and said edges slidable in said guide-hooks; a tube to receive the paper in a coiled form and suspended from said-slidable platen and having at its top a longitudinal slot, and rods revoluble in bearingls fixed on said slidable plate and said r0 5 provided with rubber sleeves which act on the said paper and adjust it vertically over said platen.

2. In a type-writer machine, the combination of a i at baselate; a ertical backplate resting on sai base-plate bent forward and forming a horizontal surface, 5, and the latter bent vertically upward and forming a vertical face-plate, 6; inclined bolts, 7, the upper ends of which are secured in the said horizontal surface and the lower ends of which are attached to the base-plate at a point farther away from the vertical backplate than said 11 per ends; a pa erholding device attache to a platen 9, w 'ch is slidable on said vertical face-plate; and a type-wheel movable toward and away from said platen.

In testimony whereof I affix my signature in presence of two witnesses;
